This side informs you about a concept of a open source DAB receiver.

[edit] Existing open DAB/DAB+/T-DMB software receiver

[edit] Software Defined DAB Receiver (complete software receiver)

• Qt-DAB (running on Linux, MacOS and Windows, using RTL2832 based USB dongles, Airspy, SDRplay, HackRF, file input)
• welle.io (running on Linux, MacOS, Android and Windows, using RTL2832 based USB dongles, file input and Airspy dongles)
• DAB receiver for gnuradio (by Zurich School of Engineering, documentation in German)

[edit] Software defined DAB receiver (up to logical layer)

• Gnuradio DAB constellation using gr-dab and USRP
• Gnuradio blocks for DAB reception (developments from Andreas Mueller, ETHZ)
  • Documentation any other information on http://www.0x7.ch/text/#index3h2
• Under construction gnuradio project on DAB+ reception on CGRAN

[edit] Software defined DAB receiver (from logical layer up to application layer)

[edit] Openmokast

Open Receiver project from CRC using RDI streams from DAB baseband receivers/decoders.

• http://www.openmokast.org

Receiver for the Psion Wavefinder

• OpenDAB

[edit] Open source DAB receiver (concept)

[edit] Goal

To develop libraries to cover all parts of a full DAB and DAB+ SDR receiver.

• Well defined library APIs
• Easy to use APIs
• Cross platform support (x86, arm, Linux, Windows, etc.)

[edit] Requirements

• Based on the SDR-J code
• Use of C++11 to use the threading feature
• Multicore support
• cmake as build environment

[edit] Architecture

Library Name	Purpose
libsdrsource	Interface to different SDR devices
libdabdemod	OFDM demodulation Frequency synchronization Time synchronization Output of the digital DAB stream
libdabdecode	DAB and DAB+ frame decoding (FIC, Superframes etc.) CRC correction Output of MPEG or ACC stream
End user program	Place holder for GUIs There can be a QT GUI, a GTK GUI or a Kodi plugin

[edit] API description

• TBD

[edit] To be discussed

• Naming of libraries
• APIs

[edit] GUI Wishlist

• Easy to use
• Channel scan
• High DPI support
• libnotify support
